Original application filed March 14, 1906, Serial No. 305,990. Divided and this application filed August 23,

Beit known that I, PETER COOPER HEWITT, a citizen ofthe United States, and resident of Ringwood Manor, county .of Passaic, lState of New Jersey, have invented certain new., and useful Improvements in High- Tension Converter Systems, or which the following is a'speciication.

In supplying the need for high tensio vapor converters,` recourse has been had to a number of expediente, some 'of which,

among others, are described and illustrated in applications for Letters Patent of the` United States led by me on the 11th day ofJanuary, 1906, Serial Numbers 293,537

Y embodiment of apparatus for serving as a high tension converter and in some .respects 13 'and 14.

the present apparatus possesses advantages whichare diderent from those set forth in the applications named.

The lnvention is illustrated 1n the accomv panying drawing, which besidescontaining a dlagram of suitable electrical circuits also showswith some detail of construction thcvapor lconverters' which I may employ 1n connection with the said system of circuits.

within an exhausted chamber or globe. 12, Y"while the chamber 10 is merely connected with a tubular element 13, terminating inside an exhausted globe or chamber 14. The entireapparatus represented by the elements 9, 11 and 12, is exhausted .to a high degree of vacuum and the same is true of the apparatus represented by the elements 10,

The electrodes 7 and 8 are positiveelectrodes, say, of iron or some other solid conducting material. At the bottom of the chamber 12 is formed a pocket in which an 1909. Serial N0. 514,331.

electrode 150i mercuryor other conducting l1qu1d'1s placed and at the lower end of the chamber 14 a similar pocket is formed con-` taining a similar electrode 16.

Leads 17 and 1S extend respectively, from the electrodes 15 and '16 to solid vpositive electrodes 19 and 20 contained in tubular elements 2l and 22 terminating inside an exhausted globe or chamber 23. 'In the circuit between thelead'l and the electrode 19 animpedance 24 maybe usually inserted and slmi-larly an yimpedance 25 is generally placed in the circuit between the lead 18 and the positive"electrode 20.

usually of mercury and it. is also provided Wlth 'a pocket adapted tocontain a supple- `mentalpositive electrode 27 joined vto one side-.of the circuit by a conductor 28 through a resistance 29. A

The electrode 26 is joined through a work l circuit 30 containing inductance and re-v sistance to an intermediate'point inthe sec- Theglobe or chamber. 23 provided with a pocket containlng a negative electrode 26,

ondary 2 of the transformer 1 2.` It will be convenient to secure the'globe or .cham''i ber 12 and the parte associated therewith as a single converter or preferably as a check \valve.' VThe same term, it will'ibe conven, -ient to apply to the globe or chamber 14 -and the parts intimately 'l associated therewith. At the Same time, theglobe23 and its connected parts may conveniently be called a' vapor converter. In any case, it will be "observed that the Well-knownvalve action of the positive electrodes in the check valve 12 ,is placed in series with the similar action taking placein the converter 23; the

same being true as related to the check valve 14 and the converter 23.

It will further be observed 'that the several positive electrodes are screened from each other and from 'the corresponding negative electrodes for electricalreasons existing within the device so'as to render it more l perfect in operation.

The converter 23 may be started by the well-known tilting method or in any other preferred way, While the check valves 12 and 1li-may be self-starting on the potential of the line.

To assist-in the starting of the last named devices I may employ starting bands 31 and devices. y

32 each being suitably connected to the leads ofthe respective oheekyalves. At the saine time, handelt-33 anal 234e `placed outsidelthe tubes 1l ancl 13 inthe neighborhood ofthe positive electrodes 7 and 8 may be utilized to strengthen the valve action of the Said positive electrodes.' v

The ,translating devices in the, work circuit 1nay he represented. by a storage battery 35, lamps 3G, 36, or any other suitable This application is a division of my application =Serial Number 305,990,71iled March lth, 190.6.
